Rupes Mark II , Mark ii NICE!

Why you say the backing plates don't fit from version 1 to version 2. Do you mean thread size, thickness of plates or something totally different. Thanks in advance.

Yes size of slot is different. Thickness is also different. Weight is identical down to the gram!

While I won't comment with 100% certainty...

The later ES (legacy, MkI) models had an enlarged tab which required a larger slot in the backing plate. The backing plates are backwards compatible (you can use a newer backing plate on an older model but you cannot use an older backing plate on a newer model).

The MK II backing plates that I have (pre-production) bolt up to the MK I, no problem. However, the earlier MK I backing plates (small slot) will not bolt up to the later MK I nor the MK II.

Also, the MK II backing plate features identical lateral or sheer strength, but significantly vertical or peel strength.

It is important to maintain lateral strength to keep the pad firmly seated on the machine and to reduce (significantly) movement loss (increase power). It took a lot of research to develop the hook on the MK II backing plate to maintain this while making the peel strength less.

The result is both the pads and backing plate will last longer as the hooks will not get straightened nor will the loops get pulled apart. Win Win

How does the Mark 2 compare to the boss regarding stalling

I constantly kept reading about how the mark1 stalled on panels which is why i ended up with the boss.
My boss hasnt stalled on me yet, and im new to machine polishing .
So obviously the bigger watt motor compensated for the stalling issue... but it does generate allot of heat wbich i feel will comprimise the pads longterm durability. .

IF you also cured the stalling issues with your more efficient motor while retaining same wattage i then think you guys took the better route
as you will generate less heat then the boss while potentionaly producing less heat then the mark 1..

Thoughts?
